Solitary Plasmacytoma of the Sternal Stalk: A Case Report and Literature Review.

Abstract Background: It has been reported that sternal neoplasms are a rare disease, accounting for about 1% of primary bone neoplasms, of which about 60% are malignancy, mostly occurring in the manubrium sternum.Case presentation: We reviewed a 77-year-old man with a solitary plasmacytoma of the sternal stalk presenting with pain in the anterior chest wall by examining a preoperative diagnosis of sternal manubrium malignant bone tumor. We performed extensive sternal manubrium tumor resection + bilateral partial costal cartilage resection + bilateral clavicular head resection + cervical lymph node dissection + thoracic reconstruction, and the postoperative recovery was perfect.Conclusion: We report a rare case of solitary plasmacytoma of the manubrium sternum successfully treated by extensive radical surgery for the manubrium tumor. Although rare, the disease should be identified, examined, and treated early to avoid serious complications.
